Lecturers

Prof T D Wilkinson, Dr F Torrisi, Prof F Udrea

Timing and Structure

Weeks 3-8 Michaelmas term and weeks 1-3 Lent term. 22 lectures, (18 on linear circuits (CD), 4 on power flow (FU), 2 lectures/week, in Michaelmas term, 3/week in Lent term.

Aims

The aims of the course are to:
  • Teach students how electrical and electronic circuits are analysed, how field effect transistors and amplifiers operate, how real and reactive power flows in a.c. circuits, and to teach basic transformer theory.

Objectives

As specific objectives, by the end of the course students should be able to:
  • Know how Ohm's law, the concepts of ideal voltage and current sources, and Thevenin's and Norton's theorems are used by electrical engineers to calculate currents and voltages in d.c. and a.c. circuits. To explain Kirchhoff's voltage and current laws and
  • Know how power is transferred from a source to a load and how any network can be represented by a Thevenin or a Norton source.(Lecture 4).
  • Understand how semiconductors can be doped to produce p-type and n-type semiconductors, introduce the p-n junction diode. (Lectures 5 & 6).
  • Know the principles of operation of the Field Effect Transistor (FET).(Lectures 6 - 8)
  • Use complex numbers in the analysis of a.c. circuits and keep track of amplitude and phase simultaneously. Understand the importance of resonance and resonant frequency in electronic circuits.(Lectures 9-12).
  • Know how an equivalent circuit for an FET can be used in transistor circuits to determine the small-signal performance of the circuits.(Lectures 13-14).
  • Calculate the gain, frequency response, and input and output impedances of amplifier circuits.(Lectures 15-16).
  • Introduction to operational amplifiers (Op Amps), and understand how feedback can be used in amplifier circuits to improve frequency response, gain stability and output and input impedances. (Lectures 17-18).
  • Understand the concepts of real, reactive and apparent power, and power factor, the importance of power factor correction of a.c. loads, the principles of operation of the transformer, and the development and use of its equivalent circuit.

UK-SPEC

The UK Standard for Professional Engineering Competence (UK-SPEC) describes the requirements that have to be met in order to become a Chartered Engineer, and gives examples of ways of doing this.
UK-SPEC is published by the Engineering Council on behalf of the UK engineering profession. The standard has been developed, and is regularly updated, by panels representing professional engineering institutions, employers and engineering educators. Of particular relevance here is the 'Accreditation of Higher Education Programmes' (AHEP) document which sets out the standard for degree accreditation.
The Output Standards Matrices indicate where each of the Output Criteria as specified in the AHEP 3rd edition document is addressed within the Engineering and Manufacturing Engineering Triposes.

The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544)

http://robotsquare.com/2013/11/25/difference-between-ev3-home-edition-and-education-ev3/ This article covers the difference between the LEGO MINDSTORMS EV3 Home Edition and LEGO MINDSTORMS Education EV3 products. Other articles in the ‘difference between’ series: * The difference and compatibility between EV3 and NXT ( link ) * The difference between NXT Home Edition and NXT Education products ( link ) One robotics platform, two targets The LEGO MINDSTORMS EV3 robotics platform has been developed for two different target audiences. We have home users (children and hobbyists) and educational users (students and teachers). LEGO has designed a base set for each group, as well as several add on sets. There isn’t a clear line between home users and educational users, though. It’s fine to use the Education set at home, and it’s fine to use the Home Edition set at school. This article aims to clarify the differences between the two product lines so you can decide which

Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide)

https://blog.strcpy.info/2016/04/21/building-a-portable-gsm-bts-using-bladerf-raspberry-and-yatebts-the-definitive-guide/ Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide) I was always amazed when I read articles published by some hackers related to GSM technology. H owever , playing with GSM technologies was not cheap until the arrival of Software Defined Radios (SDRs), besides not being something easy to be implemented. A fter reading various articles related to GSM BTS, I noticed that there were a lot of inconsistent and or incomplete information related to the topic. From this, I decided to write this article, detailing and describing step by step the building process of a portable and operational GSM BTS. Before starting with the “hands on”, I would like to thank all the pioneering Hackers and Researchers who started the studies related to previously closed GSM technology. In particul
